Full Answer

Over-the-counter, or OTC, antihistamines are also available from online retailers such as Drugstore.com, or even from Amazon.com. Many brick-and-mortar stores also have online stores, including Walgreens.com, CVS.com, and Walmart.com. Drug manufacturers often link to websites and stores where their products can be purchased, and many, such as Sudafed.com, offer coupons.

WebMD notes that common types of antihistamines include diphenhydramine, chlorpheniramine and loratadine. These drugs' common brand names are Benadryl, Chlor-Trimeton and Claritin, respectively.

OTC antihistamines, especially those taken orally, can be extremely effective in reducing allergy symptoms such as sneezing, runny nose and itching. Although these medications are readily available at many brick-and-mortar and online pharmacies, there may be side effects, and caution should be exercised while using the medicine, according to WebMD. First-generation antihistamines, such as Benadryl, can cause drowsiness or can affect coordination, so machinery should not be operated while under the influence of these drugs. Dry mouth can also occur, so WebMD suggests taking OTC antihistamines before going to sleep.
